Is it fair to say that your argument here is that "this resource was extremely valuable to me for understanding certain concepts in ways that Haskell-oriented resources in the past have not been"?

I think that's a totally fair criticism. I also believe that the Haskell resources can provide further value to you (and others in your position) over time if you choose to study them. Similarly, studying category theory or type theory or logic could.

Are these practical things to do? It depends upon your goals.
